Just finished reading this thread, lots of good information, and I think it answered my questions. I'm going to install the 87k30 dana 60 and 14 bolt, because I have them handy!
Front axel
78-95 Chevy Dodge dana 60 1 ton single axel or dually (older axels req disk conv.
77-97 Ford kingpin f350 (other years have diff. location issues)
CUCV
HUMVE
Rear axel
78-05 Chevy Dodge 14 bolt 3/4 & 1ton(disk break conv. as required, move caliper under leaf or install coilover or use a block spacer to get clearance and change location of one shock mount)
